Title: Changing-Look Quasars: Radical Changes in Accretion Rate?
Abstract: We propose to monitor via optical photometry and spectroscopy a pilot sample of high-quality changing-look quasar candidates that have existing X-ray observations. If trigger conditions are met by any candidate, we will obtain a target-of-opportunity Chandra observation, providing crucial X-ray spectral Constraints on major accretion state transitions in luminous quasars. Note: Time has already been awarded for this ToO program.
